Auto Emergency Braking has gotten extremely dangerous and locking breaks when nothing is in front of me. Always while in cruise control mode. On long extended highways, the truck will randomly slam on the brakes and skid the back tires. It has happened 6 times now. This most recent one made us slide into the next lane and I had to turn the truck into a field (~20mph) after the truck brakes went off. To avoid on coming traffic. There was a car turning around half a mile ahead and was nowhere close. Additionally, a severe issue of premature rust and degradation is occurring on the truck. 13,000 miles and the bottom looks like it's been on the road for several years.

My vehicle stalls (won't accelerate and rough idle) forcing you to roll off the highway without warning. This has happened multiple times while in cruise control going up steep hills. It shows engine misfire and check engine. I took it to the dealer multiple times and it was determined to be bad gas. I and my insurance company paid for this dealer (Hatch Toyota Show Low AZ) for complete clean and replacement of the entire fuel system. Now 5 months later it is doing it again. The safety issue is the stalling in the middle of the highway where there is no way to get out of the way of traffic. I made sure I bought good gas by paying extra money at a new Chevron gas station with new in ground tanks. But dealer claims bad gas again. That is a separate issue.

I buy a Toyota Tacoma 2021 on 5 of June 2021 in Toyota Walnut Creek California. And I have to sell it again on 15 november 2021 5 months later. Ok I was driving in a long trip of 9hrs. And I adjust the seat to be comfortable to drive but I notice that when I was looking to the front right side the mirror in the center to look to the back was in the way of my view, and I drive , moving my head down to look under the mirrorevery time when I look to the right front. A the end of the trip I get tired driving that way. Next time I was driving in Oakland Ca. I was in a stop waiting to turn to the left side in a road, and the cars in the other side in front of me the put me the high beams,and I was thinking they give me the pass, and I look around to drive,and right away 3 persons was in front of me, and thanks to GOD I don’t drive over and kill them. And I get very mad frustrated , I was ready to break the mirror with my right hand, but I control my self and don’t do it. That was when I notice the mirror and the black spot is in the mirrow is a very bad location, that take lot of view to the front right side, they need to relocated all the sensors are in that area. I sold the truck no because I can’t drive it eny more.I call Toyota I they. Don’t pat attention.

Vehicle will not hold 6th gear while in cruise control. Vehicle will suddenly down shift to 5th and sometimes 4th. This makes the vehicle surge forward abruptly.
